I'm glad you're finding tricks to help ease your fast!
My favorite is tea. I drink a lot of tea on fast days -- I buy myself really fantastic tea in all sorts of flavors. Right now I'm drinking an apricot scented black tea from Mariage Freres. I've got Earl Grey, Jasmin, Marco Polo, Cardamom and many many more. Tea gets me through.
I think your attitude is great. We need to understand we are human. Weight loss isn't necessarily fast and we *will* plateau. We *will* fall off the wagon. The difference is how we respond to it. Are we going to despair, give up and regain the weight? Or are we going to find something new? Recommit? go back to basics?
5:2 worked for me for a long time (about 40 pounds), but then I needed to tweak it in order to get it working for me again. This appears to be quite common. Some people drop carbs. Some people go to eating windows. Some track calories on their non-fast days (hate to admit it, but overeating on non-fast days can really undo all that good work). Some people have adopted the tricks in Dr. Amanda Sainsbury-Salis' books (she's fantastic and I highly recommend her books). I decided to combine 5:2 with weight watchers because some friends joined ww and asked me to join them. Thing is, you have to be flexible and when your body doesn't respond the way it had been, figure out what you need to do to get a response.
